GTC 2.0CDTI Gearbox issues

[Boroboy]

Hi All

Always felt my GTC 6spd box was a bit notchy 1st-2nd, well yesterday it finally became a more serious issue and now the car will not hold in 2nd under any load it just wants to jump back into neutral so nursed it home doing 1st - 3rd changes and dumped it on the drive.

I've built gearboxes before but not for anything Vauxhall - I have seen pics of gearboxes rebuilt in situ by removing the wheel, arch and casing to reveal gear clusters but I think that was an earlier astra possibly with M32 box. The car is about 3yr 8 month old so out of 3 year VX warranty even though it only has 25k on it. Really pissed off with it. Can these be done in situ too or is it a gearbox out job? And where might I get spare parts other than the dreaded dealership?

I'm assuming it's the dogs on 3rd gear... it changes into 2nd fine, 2nd is still there not completely blown just won't hold it

Any help would be great... towing the line between needing the car back asap but not wanting to get royally spanked taking it to VX.

Which engine do you have? I'm guessing you have the infamous m32. Will be if it's the 1.4t, 1.6t. If you have full vaux history I'd take it to vaux. As you may get up to an 80% contribution from them, even if out of warranty. If not, I'd then take it to an independent gearbox specialist. In my experience even the revised m32's have probs.
